%
%    \begin{abstract}
%       The package \texttt{CoverPage} was created to supplement
%       scientific papers with a cover page containing bibliographical
%       information, a copyright notice, and/or some logos of the author's
%       institution. The cover page is created (almost) automatically; this 
%       is done by parsing \BibTeX{} information corresponding to the
%       main document and reading a configuration file in which the author
%       can set information like the affiliation he or she is associated with.
%       
%       The cover page consists of header, body and footer; all three are 
%       macros which can be redefined using |\renewcommand|, thus allowing
%       easy customization of the package. Additionally, it should be stressed 
%       that the cover page layout is totally \emph{independent} of the 
%       main document and its page layout 
%       (which is not the easiest thing to achieve in \LaTeX).
%
%       This package requires four other packages (\texttt{keyval}, \texttt{url},
%       \texttt{textcomp}, and \texttt{verbatim}), but all of them are standard 
%       packages and should be part of every \LaTeX{} installation.
%    \end{abstract}

%    \tableofcontents
%    
%    
%    \section*{Foreword}
%
%    The best explanation for this package is an example. So first of all, 
%    please look at the file \texttt{ECCV2006Sample.pdf} which is part of 
%    this distribution. The cover page was created using 
%    the \texttt{CoverPage} package, and adding the cover page in front of the 
%    document required only adding a single line of \LaTeX{} code to the original 
%    source file.
%   
%   
%   
%   
%   
%    \section{About this Package}
%   
%    Researchers (like the author of this package) want to distribute their own work in the 
%    scientific community, either as printout or in electronic form (email or 
%    download). The scientific paper itself is sufficient for this purpose, but 
%    it is not optimal for several reasons:
%    \begin{itemize}
%    \item
%       Other scientists need \emph{bibliographical information} on the paper 
%       in order to cite it properly. So let us be nice to our colleagues and 
%       attach this necessary information to the paper in some way.
%    \item
%       One should not ignore the legal subtleties. If papers are published in 
%       some journal or conference proceedings, one does not own the copyright 
%       anymore; this is especially problematic if the paper shall be 
%       available for download. Fortunately, most publishers have now realized 
%       that researchers \emph{need} to put their work on their homepages 
%       (otherwise, the work is widely ignored). Therefore, most publishers 
%       allow redistribution for scientific use provided that some special 
%       \emph{copyright notice} is attached to the paper.
%    \item
%       Last, but not least, we want our colleagues to recognize the logos of our
%       excellent work group and our great university. Scientific papers are 
%       characterized by highly different page layouts, while a unified look of 
%       cover pages together with logos can help to establish a 
%       recognizable \emph{corporate design}.
%    \end{itemize}
%    All three aims can be reached by supplementing the paper with an additional cover 
%    page which contains all the required information. This is exactly the purpose 
%    of the \texttt{CoverPage} package -- and it does this job in a widely automated way.
%
%
%
%
%
%    \section{Installation}
%
%    The package \texttt{CoverPage} is distributed as \texttt{dtx} archive together
%    with a corresponding \texttt{ins} installation script. Advanced \LaTeX{} users 
%    who know these file types may now install the package in the usual \LaTeX{} way
%    and skip the remainder of this section.
%    
%    For all others: \texttt{dtx} files are text files which combine \LaTeX{} code with 
%    its own code documentation. The whole \LaTeX{} base system and almost all standard
%    packages are distributed in this form. In order to install such files, you must
%    \begin{enumerate}
%    \item
%      Enter \texttt{latex CoverPage.ins} at the command line. This extracts all 
%      necessary files from the archive (here: the \texttt{CoverPage.sty} style file
%      and a \texttt{CoverPage.cfg} configuration file.
%    \item{}
%      [optionally:] Enter \texttt{latex CoverPage.dtx} at the command line. 
%      This produces a documentation of the package (user interface and code documentation). 
%      ^^A Package documentations often include their own \texttt{sty} file for demonstration
%      ^^A purposes, so the order usually \emph{is} important. However, this is not the case for 
%      ^^A \texttt{CoverPage}.
%    \end{enumerate}
%    Note that the documentation \texttt{CoverPage.pdf} which is distributed with the 
%    package only contains the user interface. If you also want to take a look at the 
%    commented source code, you have to execute the step described above.
%    
%    
%    \section{Setup and Usage}
%
%    This package can do its job more or less automatically, but you also have access 
%    to every setting if you want to modify some behaviour by hand.
%    
%    
%    \subsection{Automatic cover page creation}
%
%    Ideally, you have to include just one line in your \LaTeX{} document:
%    \begin{verbatim}
%    \usepackage{CoverPage}
%    \end{verbatim}
%    That's all. But in order to make automatic cover page creation
%    work properly, you have to do two things in advance:
%    \begin{itemize}
%    \item
%       You have to create a text file containg the \BibTeX{} entry of your document. 
%       The file name must be \meta{mainTeXFileName}\texttt{.BibTeX.txt}. For instance, if
%       you entered \texttt{pdflatex myPaper.tex} on the command line (or let some
%       specialized editor issue this command), then 
%       the corresponding bibliographical information (and nothing more!) should be put in 
%       the file \texttt{myPaper.BibTeX.txt}.
%    \item
%       Even after parsing the \BibTeX{} data, the \texttt{CoverPage} package cannot know 
%       your institute, postal adress, or university logo. Fortunately, this missing data 
%       is not specific to the document, but can be specified once and for all, 
%       namely in the \texttt{CoverPage.cfg} configuration file.
%    \end{itemize}
%    As the cover page is directly printed at the |\begin{document}| command, 
%    it is clear that all cover page data settings must appear \emph{before} this command, i.e. 
%    in the preamble. There are three different ways how texts get on the cover page: 
%    parsing of the \BibTeX{} entry, settings in the config file \texttt{CoverPage.cfg}, and user input in 
%    the document preamble (in this order). Note that later settings can 
%    overwrite previous ones.
%
%
%    \subsection{Options}
%
%    By using |\usepackage[|\meta{optionList}|]{CoverPage}|, the user can specify 
%    package options. Four such options are currently supported.
%
%    The language options \texttt{german} and \texttt{english} set some language-specific string in 
%    auto-generated document source strings. If no language is specified, it defaults to English.
%    
%    The option \texttt{twoside} is intended for two-sided printouts. In this case, we want the
%    original document to start on an odd (right) page, so the package will print the cover page
%    followed by a further empty page (the back side of the cover page).
%    
%    The last possible option is \texttt{nobib}. If no \BibTeX{} file exists, this package will 
%    stop with an error. The |nobib| option disables this behaviour and allows to proceed
%    normally. Then, the cover will not contain a \BibTeX{} reference and the user will have to 
%    set all texts manually because no \BibTeX{} file can be parsed for the relevant data.
%
%
%    \subsection{Setting cover page data by hand}
%
%    Setting of cover page data either in the config file or in the document preamble
%    is done with the same commands. In fact, it is just one single command (and a 
%    few macros, like fonts, which can be redefined using |\renewcommand|).
%
%    \DescribeMacro{\CoverPageSetup}
%    The command |\CoverPageSetup{|\meta{CommaSeparatedList}|}| uses the 
%    \texttt{keyval} package to provide a user-friendly interface for setup of 
%    the cover page. The \meta{CommaSeparatedList} consist of pairs 
%    \meta{key}|=|\meta{value}. If \meta{value} contains one or more 
%    commas, it must be enclosed in braces. A good example is the setting of the 
%    institute which can be centralized in the config file:
%    \begin{verbatim}
%    \CoverPageSetup{institute =
%    {Institute of Imaging and Computer Vision\\
%     RWTH Aachen University, 52056 Aachen, Germany\\
%     tel: +49 241 80 27860, fax: +49 241 80 22200\\
%     web: www.lfb.rwth-aachen.de}}
%    \end{verbatim}
%    Allowed keys are:
%    \begin{itemize}
%    \item
%       The keys |title|, |author|, |institute|, |insource|, and 
%       |copyright| set the corresponding texts in the cover page.
%    \item
%       An automatic copyright notice can be created with |year = |\meta{year} 
%       and a known |publisher| key. In the current version, the package 
%       recognizes |Springer| (copyright text is correct for lecture notes
%       on computer science (LNCS) series), |Kluwer|, |SPIE| and |IEEE|. For these 
%       publishers, the copyright notice requested by the corresponding publisher is 
%       created automatically.
%    \item
%       An automatic source information is created if the keys |booktitle| or 
%       |journal| are defined. In this case, the source text reads: ``in: 
%       \meta{booktitle$\vert$journal}. \meta{referenceToBibTeXEntry}'' where 
%       \meta{referenceToBibTeXEntry} is a language dependent text. The 
%       current version supports the package options \texttt{german} and 
%       \texttt{english} (default).
%    \end{itemize}
%    Note that parsing the \BibTeX{} entry routes the information through the same 
%    \texttt{keyval} interface which is also used for the manual setup. 
%    The above information on the automatic generation 
%    of copyright or source information also holds if the \BibTeX{} entry contains 
%    the necessary keywords. Currently supported \BibTeX{} type identifiers are 
%    |@article|, |@inproceedings|, |@incollection|, and |@misc|.
%
%
%    \subsection{Customization}
%
%    \DescribeMacro{\CPTitleFont}
%    \DescribeMacro{\CPAuthorFont}
%    \DescribeMacro{\CPInstituteFont}
%    \DescribeMacro{\CPInSourceFont}
%    \DescribeMacro{\CPCopyrightFont}
%    The five texts for title, author, institute, source, and copyright are all 
%    associated with an individual font. The standard definitions are
%    \begin{verbatim}
%    \newcommand{\CPTitleFont}{\Huge\sffamily\bfseries\upshape}
%    \newcommand{\CPAuthorFont}{\LARGE\sffamily\mdseries\upshape}
%    \newcommand{\CPInstituteFont}{\Large\sffamily\mdseries\upshape}
%    \newcommand{\CPInSourceFont}{\large\sffamily\mdseries\upshape}
%    \newcommand{\CPCopyrightFont}{\large\sffamily\mdseries\upshape}
%    \end{verbatim}
%    but you can change these setting with |\renewcommand|.
%
%    \DescribeMacro{\CoverPageHeader}
%    \DescribeMacro{\CoverPageBody}
%    \DescribeMacro{\CoverPageFooter}
%    \DescribeMacro{\CoverPageFooterLogo}
%    The cover page consists of three parts: header, body, footer. These parts are 
%    encapsulated as macros which allow redefinition. For instance, the header is 
%    empty by default, but
%    \begin{verbatim}
%    \renewcommand{\CoverPageHeader}{%
%       \includegraphics[width=\textwidth]{lfbheader}}
%    \end{verbatim}
%    tells \texttt{CoverPage} to use a graphics, scaled to full width. The same holds for 
%    |\CoverPageBody| and |\CoverPageFooter| (cf. code documentation at the 
%    end for the default definitions). The footer, however, contains more or less 
%    fixed parts (\BibTeX{} info and copyright notice), so it offers another point of
%    entry for easy user customization: The macro |\CoverPageFooterLogo| defines the 
%    contents of the lower right corner; for instance, this could be used to display 
%    a university logo.
%
%    Costumization commands which are needed on a regular basis should be put in 
%    the config file \texttt{CoverPage.cfg}. Please do not modify the style file
%    \texttt{CoverPage.sty} directly.
%

%
%
%    \section{Implementation Part I -- Initialization}
%
%    From now on, we describe the code of the file \texttt{CoverPage.dtx}.
%    It is mainly intended for the advanced \LaTeX{} user who wants to understand
%    how this package works.
%
%
%    \subsection{Identification}
%
%    The first line indicates the begin of the \texttt{CoverPage.sty} code.
%    Then we check that the \LaTeX{} version is not too old and the package
%    identifies itself.
%
%    \begin{macrocode}
%<*CoverPage>
\NeedsTeXFormat{LaTeX2e}[1999/12/01]
\ProvidesPackage{CoverPage}%
  [2006/02/23 v1.01  automatic cover page generation  (MM)]
%    \end{macrocode}
%
%
%    \subsection{Required Packages}
%
%    We need the following packages:
%    \begin{itemize}
%    \item
%      \texttt{keyval}: our package can be customized using the \texttt{keyval}
%      interface, which is e.g. known from the \texttt{graphicx} package.
%    \item
%      \texttt{textcomp}: mainly for |\textcopyright| (the \textcopyright{} symbol)
%    \item
%      \texttt{url}: for typesetting URLs.
%    \item
%      \texttt{verbatim}: listing of the \BibTeX{} entry.
%    \end{itemize}
%    These are the next four lines of our code:
%    \begin{macrocode}
\RequirePackage{keyval}
\RequirePackage{textcomp}
\RequirePackage{url}
\RequirePackage{verbatim}
%    \end{macrocode}
%
%
%    \subsection{Switches and options}
%
%    Now we can implement the options.
%    The macros |\CP@BibRef| (default: ``See also \BibTeX{} entry below.'') 
%    and |\CP@In| (default: ``in:'') are initialized in English and can be
%    overwritten by language options (no further action is necessary for |\CP@In| 
%    as German and English, the only supported languages in this version, are
%    identical here).
%
%    For the option |twoside| (two-sided printout; cover page must get a blank
%    back side), we define a command which is to be appended at the end of 
%    the cover page creation macro. By default, it does nothing, but with the 
%    |twoside| option, we pass an empty box to |\shipout| instead, thus printing
%    an empty page. Note that global options are automatically passed on to 
%    packages, so specifying |twoside| as option in |\documentclass| should be
%    sufficient.
%    \begin{macrocode}
\newif\ifCP@nobib\CP@nobibfalse
\gdef\CP@BibRef{See also \BibTeX{} entry below.}
\gdef\CP@In{in:}
\let\CP@AdvancePageTwoSided\relax
\DeclareOption{german}{\gdef\CP@BibRef{Siehe auch \BibTeX{} Eintrag unten.}}
\DeclareOption{english}{\gdef\CP@BibRef{See also \BibTeX{} entry below.}}
\DeclareOption{twoside}{\gdef\CP@AdvancePageTwoSided{\setbox255\vbox{}\shipout\box255}}
\DeclareOption{nobib}{\CP@nobibtrue}
\ProcessOptions\relax
%    \end{macrocode}
%
%
%    \subsection{New register definitions}
%
%    Our cover page shall have 0.75 inch margin on each side. Width and height are defined
%    in the two dimension registers |\CP@CoverPageWidth| and |\CP@CoverPageHeight| 
%    which we first define and then compute from the total paper size.
%    
%    \begin{macrocode}
\newdimen\CP@CoverPageWidth
\newdimen\CP@CoverPageHeight
\CP@CoverPageWidth=\paperwidth
\CP@CoverPageHeight=\paperheight
\advance\CP@CoverPageWidth by -1.5in
\advance\CP@CoverPageHeight by -1.5in
%    \end{macrocode}
%
%
%    \subsection{Text macros}
%
%    The text on the cover page consists of five macros: title, author, institute, the 
%    source where the paper can be found and a copyright notice.
%
%    \begin{macrocode}
\def\CP@Title{title undefined}
\def\CP@Author{author undefined}
\def\CP@Institute{institute undefined}
\def\CP@InSource{source undefined}
\def\CP@Copyright{\textcopyright{} copyright by the author(s)}
%    \end{macrocode}
%
%    Additional, we define macros for constructing source and copyright notice
%    automatically.
%
%    \begin{macrocode}
\def\CP@Year{(unknown year)}
\def\CP@Source{(unknown source)}
%    \end{macrocode}
%
%    At the end, we `steal' a definition from the \texttt{doc} package.
%
%    \begin{macrocode}
\@ifundefined{BibTeX}
   {\def\BibTeX{{\rmfamily B\kern-.05em%
    \textsc{i\kern-.025em b}\kern-.08em%
    T\kern-.1667em\lower.7ex\hbox{E}\kern-.125emX}}}{}
%    \end{macrocode}
%
%
%
%
%
%    \section{Implementation Part II -- Internal Commands}
%
%    This section contains some internal commands defined in \texttt{CoverPage}.
%    These macros all start with |CP@|; please do not use them because they
%    are not part of the user interface and might be redefined in future versions.
%
%
%    \subsection{Define and read bibliography file}
%    
%    If \texttt{nobib} option is not set, do the following:
%    Check if file exists. If so, store argument of |@inproceedings| or 
%    |@article| for later parsing. In order to achieve this, we temporarily (i.e. 
%    locally) define macros |\inproceedings| and |\article| and tell \LaTeX{} 
%    that the |@| has category code 0 (i.e. it starts macros) when reading the file.
%    
%    After execution of |\article| or any of the other similar commands,
%    |\CP@ParseArg| contains the argument of the \BibTeX{} entry. 
%    Later on, when parsing the argument, we must throw away the \BibTeX{} keyword
%    and the comma which it seperates from the interesting \meta{key}|=|\meta{value}
%    list. This is the reason why |\CP@ParseArg| is initialized with |dummy,|.
%    If the \BibTeX{} file does not exist, we report an error.
%    \begin{macrocode}
\gdef\CP@ParseArg{dummy,}
\ifCP@nobib
\else
  \IfFileExists{\jobname.BibTeX.txt}{%
    \bgroup
      \catcode`\@0
      \bgroup
        \def\inproceedings##1{\xdef\CP@ParseArg{##1}}%
        \def\article##1{\xdef\CP@ParseArg{##1}}%
        \def\incollection##1{\xdef\CP@ParseArg{##1}}%
        \def\misc##1{\xdef\CP@ParseArg{##1}}%
        \input{\jobname.BibTeX.txt}%
      \egroup
    \egroup
  }{%
    \PackageError{CoverPage}{No BibTeX file (\jobname.BibTeX.txt) found!}%
      {you must provide a \jobname.BibTeX.txt file}%
  }
\fi
%    \end{macrocode}
%    
%    
%    \subsection{Interface setup (with \texttt{keyval})}
%
%    We then define a series of \texttt{keyval} keys which will be used by both 
%    \BibTeX{} parser and user interface. The first commands are for automatic 
%    creation of source data.
%    
%    The source field is defined as "in: \meta{source}", followed by a language-specific
%    reference to the \BibTeX{} entry if the \BibTeX{} class defines defines a 
%    main source of reference. Predefined are: |booktitle| (e.g. for |@inproceedings|) and
%    |journal| (for |@article|).
%
%    \begin{macrocode}
\def\CP@SourceGiven{\gdef\CP@InSource{\CP@In\ \CP@Source. \CP@BibRef}}
\define@key{CoverPage}{booktitle}{\gdef\CP@Source{#1}\CP@SourceGiven}
\define@key{CoverPage}{journal}{\gdef\CP@Source{#1}\CP@SourceGiven}
%    \end{macrocode}
%    
%    The next five keys define the five default text strings.
%    
%    \begin{macrocode}
\define@key{CoverPage}{title}{\gdef\CP@Title{#1}}
\define@key{CoverPage}{author}{\gdef\CP@Author{#1}}
\define@key{CoverPage}{institute}{\gdef\CP@Institute{#1}}
\define@key{CoverPage}{insource}{\gdef\CP@InSource{#1}}
\define@key{CoverPage}{copyright}{\gdef\CP@Copyright{#1}}

%    \subsection{Parsing and interpretation of the bibliography file}
%
%    We parse the \BibTeX{} file using a two step macro expanding mechanism to eliminate 
%    the \BibTeX{} keyword.
%    One should also mention that we (locally) disabled errors for unknown keys in 
%    \texttt{keyval}. The macro |\KV@errx| which is used here is no part of the official
%    \texttt{keyval} user interface, but it is the only way to do it; we do not want to
%    disable \texttt{keyval} error checking in general.
%    \begin{macrocode}
\gdef\CPProcessBibEntry{%
    \edef\temp{\noexpand\CP@killBibTeXKeyword\CP@ParseArg\par}%

%
%    \subsection{Printing of cover page}
%
%    The printing of a page whose page layout is different from the remaining document 
%    is a difficult job. We solve this by going deep down to \TeX{} internals, namely 
%    the |\shipout| procedure which is called every time a page is assembled 
%    completely (which is always done in the internal box register 255). We just compile 
%    our own box 255 and give it to |\shipout|. Note the shift of the upper left 
%    corner; this is due to the fact that the reference point is 1 inch from left and top
%    paper border.
%    \begin{macrocode}
\newcommand{\CP@PrintCoverPage}{\bgroup\global\setbox255\vbox{%
    \vspace*{-.25in}%
    \noindent\hspace*{-.25in}%
    \rlap{\begin{minipage}[t][\CP@CoverPageHeight][c]{\CP@CoverPageWidth}%
        {\CoverPageHeader}%
        \vfill%
        {\CoverPageBody}%
        \vfill%
        {\CoverPageFooter}%
    \end{minipage}}%
}\egroup\shipout\box255}
%    \end{macrocode}
%
% This function is automatically called at |\begin{document}|. Additionally, we
% advance a page in two-sided mode.
%
%    \begin{macrocode}
\AtBeginDocument{\CP@PrintCoverPage\CP@AdvancePageTwoSided}

%
%    \section{Implementation Part III -- User Interface}
%
%    All macros explained in the `Usage' section can be found here.
%    The user can change fonts, has access to the \texttt{keyval} interface and can 
%    redefine cover page composition. Change with |\renewcommand| if you want to.
%    
%
%    \subsection{Set fonts}
%
%    We first define fonts for the five main text areas.
%
%    \begin{macrocode}
\newcommand{\CPTitleFont}{\Huge\sffamily\bfseries\upshape}
\newcommand{\CPAuthorFont}{\LARGE\sffamily\mdseries\upshape}
\newcommand{\CPInstituteFont}{\Large\sffamily\mdseries\upshape}
\newcommand{\CPInSourceFont}{\large\sffamily\mdseries\upshape}
\newcommand{\CPCopyrightFont}{\large\sffamily\mdseries\upshape}
%    \end{macrocode}
%    
%    
%    \subsection{Access to \texttt{keyval} interface}
%    
%    Pass arguments on to \verb!\setkeys! from \texttt{keyval} package.
%    \begin{macrocode}
\newcommand{\CoverPageSetup}[1]{\setkeys{CoverPage}{#1}}
%    \end{macrocode}
%    
%    
%    \subsection{Definition of cover page}
%    
%    The header is empty by default:
%    \begin{macrocode}
\newcommand{\CoverPageHeader}{}
%    \end{macrocode}
%    
%    The body consists of: [rule] - title --- author - institute --- source - [rule]
%    
%    \begin{macrocode}
\newcommand{\CoverPageBody}{%
    \parbox{\linewidth}{%
        \centering%
        \rule{\linewidth}{1.5pt}\par
        \vspace*{2mm}
        {\CPTitleFont\CP@Title\par}
        \vspace{5mm}
        {\CPAuthorFont\CP@Author\par}
        \vspace{1mm}
        {\CPInstituteFont\CP@Institute\par}
        \vspace{5mm}
        {\CPInSourceFont\CP@InSource\par}
        \vspace*{2mm}
        \rule{\linewidth}{1.5pt}\par
    }%
}
%    \end{macrocode}
%    
%    The footer contains the \BibTeX{} entry, the copyright notice and info/logo
%    at the bottom.  Footer info is some document info; the logo is empty by default.
%    
%    \begin{macrocode}
\newcommand{\CoverPageFooter}{%
    \normalfont
    \ifCP@nobib
    \else
        \noindent\textsf{\large \BibTeX:}
        {\small\verbatiminput{\jobname.BibTeX.txt}\par}%
        \vspace{5mm}%
    \fi
    {\CPCopyrightFont\CP@Copyright\par}
    \vspace{10mm}
    {\CoverPageFooterInfo\hfill\CoverPageFooterLogo}
}
\newcommand{\CoverPageFooterInfo}{%
    \parbox[b]{.5\textwidth}{%
        \tiny document created on: \today\\
        created from file: \texttt{\jobname.tex}\\
        cover page automatically created with \texttt{CoverPage.sty}\\
        (available at your favourite CTAN mirror)%
    }%
}
\newcommand{\CoverPageFooterLogo}{}
%    \end{macrocode}
%
%
%
%
%
%    \subsection{Start actions}
%    
%    At the end of this package, we process \BibTeX{} entry and read the config file. 
%    The order is important: if both contain e.g. an entry for \texttt{institute}, the 
%    last setting overrides the first one. The config file is given the higher priority 
%    here.
%
%    \begin{macrocode}
\CPProcessBibEntry
\IfFileExists{CoverPage.cfg}%
    {\input{CoverPage.cfg}}%
    {\PackageWarning{CoverPage}{No config file (CoverPage.cfg) found!}}
%</CoverPage>
%    \end{macrocode}
%
%    The |%</CoverPage>| guard signals the end of the \texttt{CoverPage.sty} code.
%
%
%
%
%
%    \section{Config File}
%
%    The code for the sample config file is also stored in \texttt{CoverPage.dtx}.
%    It is written to \texttt{CoverPage.cfg} including all comments and without
%    preamble or postamble from \texttt{docstrip} such that it is easy to understand
%    for the human user.
%
%    \begin{macrocode}
%<*CoverPageCFG>
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

%%
%%  This file "CoverPage.cfg" is read by "CoverPage.sty"
